ASSEMBLY
 Wipe a drop of oil onto the inner blade washer and the
outer blade washer where they contact the blade.
WARNING:
If inner blade washer has been removed, replace
it before placing blade on spindle. Failure to do
so could cause an accident since blade will not
tighten properly.
 Fit saw blade inside upper blade guard and onto shoulder
of inner washer. The blade teeth point downward at the
front of saw as shown in figure 13.
 Replace the outer blade washer. The double "D" flats on
the blade washers align with the flats on the spindle.
 Depress spindle lock button and replace blade bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt counterclockwise to tighten.
CAUTION:
Always install the blade with the blade teeth and
the arrow printed on the side of the blade pointing
down at the front of the saw. The direction of blade
rotation is also stamped with an arrow on the upper
blade guard.
 Tighten blade bolt securely.
 Replace blade bolt cover and tighten blade bolt
coverscrew securely.
 Lower the blade guard.
 Raise and lower the saw arm to ensure lower blade guard
functions correctly.
WARNING:
Make sure the spindle lock button is not engaged
before reconnecting saw into power source. Never
engage spindle lock button when blade is rotating.
CUTTING A SLOT IN THE ZERO CLEARANCE
THROAT PLATE
In order to use your compound miter saw, you must cut
a slot through the zero clearance throat plate to allow for
blade clearance. To cut the slot, set your saw at 0° bevel,
turn saw on and allow the blade to reach full speed, then
carefully make a straight cut as far as it will go through the
throat plate. Turn your saw off and allow the blade to come
to a complete stop before raising the saw arm.
Adjust both sliding miter fences to insure proper clearance
prior to making a bevel cut. Set the bevel angle (right) to 48°,
turn your saw on and allow the blade to reach full speed,

then carefully make another cut through the zero clearance
throat plate. Next, set the bevel angle (left) to 48°, turn your
saw on and allow the blade to reach full speed, then carefully
make another cut through the zero clearance throat plate.
The slot in the throat plate will then be wide enough to allow
the blade to pass through it at any angle from 0° to 48°. Reset
the position of the sliding miter fences.
DANGER:
Laser radiation. Avoid direct eye contact with light
source.
WARNING:
Use of controls, adjustments, or performance of
procedures other than those specified here can
result in hazardous radiation exposure.
WARNING:
The laser guide is powered by the AC power supplied
to the saw. User must lock out the trigger switch
prior to aligning or performing any maintenance
on the laser. Failure to lock out the trigger switch
could lead to inadvertent actuation of the miter
saw which could result in serious personal injury.
